Judging from this story, how do you think the author, ambrose bierce, views war?

For the answer to the question above, an Occurrence at Owl Creek Bridge is a short story written by eternal pessimist Ambrose Bierce in 1890. It's set in the Civil War, 30 years prior. 
Bierce actually fought in the Civil War, he was enlisted for the Union's 9th regiment and was active at the Battle of Shiloh. That being said, Bierce has real life experience with war, something that is really reflected in Owl Creek Bridge. He sees that the war is treacherous and brutal. The events that seemingly occur are highly romanticized, as war is often portrayed by the government, media, etc. However, the ending is the biggest key into Bierce's thoughts on war. War and death can not be dramatized, they can only be realized as a cold and unforgiving force.
